I replaced the broken input jack but not the surround. The surround has a small piece missing so it's not as bad as I made it out to be. The surround is not breaking down - it looks more like something bumped into it. I've listened to the speakers and they sound great and the bass is surprisingly good. I haven't pushed them much but at low to moderate listening levels they reproduce the sound quite well. I do need to find out what surround works best with the driver as it has a longer excursion than most.
